Before we showed you how Taylor Swift had T.I., Nelly, and Young Jeezy backstage at her concert in Atlanta last night– now, see out the performance the southern rappers were in the building for! T.I. joined Taylor on stage to perform the smash hit “Live Your Life”… move over Rihanna! “Singing Live Your Life with TI tonight was unreal. LOUDEST screams from the crowd, 14,000 people, hands in the air-welcome back @Tip!” she tweeted. Check out the two rocking the stage after the jump!!
